The cloud is everywhere even though we rarely notice it. You interact with the cloud starting first thing in the morning as you check your phone for new emails before you even get out of bed or use your phone’s maps app to check the traffic conditions on the way to work. When we go home, we may open up vacation photos a friend sent to us on Dropbox or upload a file to Google Drive without giving it a second thought.

All of these are cloud services, yet we experience them in completely different ways, which raises the questions: What is a cloud service? Where is the cloud? and What is the difference between the cloud and the internet?  

These are the three basic types of cloud services:

  • Software as a service (SaaS) is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the Internet.
  • Infrastructure as a service (IaaS) is a form of cloud computing that provides virtualized computing resources over the internet.
  • Platform as a service (PaaS) or platform-based service is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.

Cloud services provide great flexibility in provisioning, duplicating and scaling resources to balance the requirements of users, hosted applications and solutions. Cloud services are built, operated and managed by a cloud service provider, which works to ensure end-to-end availability, reliability and security of the cloud.

These are the four types of cloud computing models:

  • Private cloud: The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers. It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises.
  • Community cloud: The cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns. It may be owned, managed, and operated by one or more of the organizations in the community, a third party, or some combination of them, and it may exist on or off premises.
  • Public cloud: The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them. It exists on the premises of the cloud provider.
  • Hybrid cloud: The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability.

Cloud computing makes computer system resources, especially storage and computing power, available on demand without direct active management by the user. The term is generally used to describe data centers available to many users over the Internet.
